Title: Production of coloured photographic images
IPC: G03C7/28
Filed: 1941-12-05
Abstract: 553,879. Coloured photographic images. TULL, A. G. Dec. 5, 1941, No. 15707. [Class 98 (ii)] A silver halide emulsion layer is weakly dyed with an acid dye during manufacture, and treated after exposure, development, and dye-destruction with a solution of a basic dye to form a dye lake image of normal intensity. The basic dye solution may be applied after exposure but before dye-destruction. Suitable basic dyes are Auramine, Acronol Yellow and Rhodamine, and a suitable acid dye Metanil yellow. In the dye-destruction process, an acid dye is used which permanently stains the layer ; alternatively a precipitating agent is present in the layer. A blue sensitive silver halide emulsion containing Metanil Yellow is after exposure and development processed by the dye-destruction process, e.g. using a thiourea-sulphuric acid dye-destruction bath, or using a calcium hypochlorite-acetic acid bath to destroy the dye at the points free of silver. The layer is treated with a solution of Auramine or Acronol Yellow, which is precipitated imagewise, and the layer is washed. The basic dye may be of a different colour from the acid dye. The images in other layers of multilayer material may be processed by chemical toning.

Filed: 1927-06-20
Abstract: 299,076. Baird, J. L., and Baird Television Development Co., Ltd. June 20, 1927. Copying-telegraphs. - In a picture-telegraph system of the type in which a photographic record is produced at the receiving station, the picture to be transmitted is cut into strips which are joined end to end and scanned in two dimensions. In this way a picture of any desired size can be telegraphed. At the receiving station the picture is recorded in strip form. The strip is then cut up into lengths (which may be marked off by the synchronising signals) and re-arranged to form the picture. Fig. 3 (plan), shows the transmitter in which the strip formed as described above is wound off a drum 12 on to a drum 10 through a guide 26 and exposed to illumination by two lamps 30 through an opening 28. The exposed portion of the strip is scanned by spirally arranged lenses 2, which throw a moving image of it upon a light-sensitive cell 8 controlling the signal circuit. The scanning disc 4, carrying the lenses 2, is mounted on the motor-driven shaft 22, to which the tape-feed shaft 18 can be clutched by operating the clutch handle 36. In a modification, a fixed lens may take the place of the scanning disc and scanning may be effected by the movement of a radially slotted disc co-operating with a fixed transverse slot. The receiving apparatus is similar, mutatis mutandis, to the transmitting apparatus. In a modification, a spot of light may be traversed across the band somewhat as described in Specification 269,658. The picture at the transmitting station may control the cell 8 by transmitted or reflected light.

Title: Control of gas turbine engines

Abstract: 683,391. Gas turbines. ARMSTRONG SlDDELEY MOTORS, Ltd., and PARKER, A. July 10, 1950 [June 22, 1949], No. 16542/49. Class 110(iii) [Also in Group XXXV] The temperature of a gas turbine aircraft engine is controlled in accordance with the difference between a reference voltage developed in unit 26, Fig. 3, and preset by lever 41 which also operates a main fuel control device 43, and a voltage developed by a photo-electric cell 11 responsive to the temperature of the turbine blades. The difference voltage is amplified in unit. 28, 31 which gives an a.c. output proportional to the blade Àtemperature deviation from a preset value for application to the stator windings 54 of an a.c. servo-motor having a second pair of constantly energised stator windings 55. The motor also includes windings 57 for supplying a feed-back voltage to the amplifier unit 28, 31. Upon a temperature deviation the motor operates a fuel valve 51 through reduction gearing 61 and rack 63. The valve 51 may be arranged to augment the main fuel control device 43 taking fuel from a pipe 46 fed from a pump 44, in which case the control device 43 is set for maximum fuel supply in Arctic conditions, e.g. 90 cu. units per unit of time, or may alternatively be arranged to bleed the supply line 47, feeding back fuel to the pipe 45 over pipe 67 in which case the control device 43 is set for maximum fuel supply in tropical conditions, e.g. 130 cu. units per unit of time. In a further embodiment Figs. 4 and 5, (not shown) the amplifier unit 28, 31 provides a d.c. output for energising a solenoid which operates a half-ball valve in the supply line 66, 50 against the action of a spring. The photo-cell 11, Fig. 1, is shielded from extraneous light by a container 13 mounted by a bracket 18 on the outlet manifold of the compressor. The photo-cell picks up radiation from a turbine blade 12 through a tube 14 and quartz window 16 which serves to seal off turbine gases. The tube may be cooled by means of cooling air passed through a jacket 22. Thermocouples may be used instead of photo-cells. The amplifier 28, 31 may be electronic or magnetic and the Provisional Specification states that an electronic bridge may be used to feed a magnetic amplifier.
